Comments on Castle Defense Online for Android

★★★★★ Great game. Takes some grind to start but once you find a few people yo play with you can rank up and get relics much quicker. Don't stop playing just bc you don't see anyone on at the moment, they may be in a game or mining for ores. Once there is a more active player base this game will be amazing

★★★★★ In my opinion, I think this game is valid. Stradigy game✅️ Good community And it is fun for new players HEAKS NAHH Fix this but its so fun when you get good like Booey and Raptor. this is my sister acount

★★☆☆☆ The game is OK but needs a lot of work. The room system should be rank based que of some kind, but the player base is way too small. Too many buttons don't work, and goals are locked behind ads which aren't even available. The defense feels impossible to play because you either don't have enough players to play at your level, have someone entirely OP on the squad that takes the fun out of playing, or everyone joins is so new and weak you can't play any level higher than the first 3 over and over

★★☆☆☆ Character audio is too repetitive, movement is janky, you can't do anything really with the controls, you don't have an option to skip the tutorial your just thrown right in. for some reason on the top left theirs health and mana bars I think? They don't move. And theirs too much clutter on the screen. It feels like the early 2000s free to play games, and not the good kind either. If more work was put into it and more thought I feel like it can be better. But i don't find it enjoyable honestly.
